Abstract

Background: A common practice is not to operate on patients with elevated blood pressure (BP) levels to avoid cardiovascular and cerebrovascular complications. We therefore designed a study to evaluate the effect of prolonged surgery under local anesthesia on BP levels, and to compare the outcome of patients with elevated BP to those with normal BP.

Methods: We studied 121 patients (65 males) with a mean age of 60 ± 14 years (range 31-89) who were referred for Mohs micrographic surgery (MMS) during 2 consecutive months. Forty six patients had a history of hypertension. Blood pressure was measured in all subjects in the supine position with an automated device 5 times during surgery.

Results: Blood pressure decreased significantly during surgery from 152 ± 2/85 ± 1 mm Hg at baseline to 139 ± 2/79 ±1 at the end of the surgery (p < .05). Forty two patients (34%) had elevated BP levels at baseline whereas only 18 patients had these levels at the end of the first stage. There was no difference in surgery outcomes between those with elevated and those with normal BP levels at baseline.

Conclusions: Blood pressure levels decrease during MMS under local anesthesia and the outcome of patients with elevated BP is good. Thus, patients with elevated BP can safely undergo surgery under local anesthesia
